Secure and competitively priced energy supply

Uniper operates a range of assets in Sweden, including low-carbon hydro and stakes in nuclear power stations. We also operate a number of gas-fired and oil-fired generating units used primarily as reserve capacity to ensure grid stability.

Nuclear power, which meets about half of Sweden’s power demand, plays an important role in its energy supply. Uniper is the majority owner of the nuclear power plant (NPP) Oskarshamn and a minority owner of the Ringhals and Forsmark NPPs. We also own Barsebäck, Sweden’s first commercial NPP, which has been decommissioned and is currently being dismantled. The highest priorities of our nuclear power business are responsibility and safety.

Together with nuclear power, hydroelectricity meets Sweden’s baseload needs. Our low-carbon hydro plants provide both stability and flexibility to the country’s energy system.

To keep Swedish industry running, it needs a reliable supply of electricity 24/7. That’s why our experts focus on delivering the secure, sustainable, and competitively priced energy that Sweden and its industry depend on.

Hydropower

Uniper is the third-largest hydropower producer in Sweden. From Sundsvall, we manage 76 run-of-river plants, located from Lycksele in the North to Kristianstad in the South.

The plants have a combined capacity of about 1,600 MW and an average annual output of 8 TWh; this is about 12% of Sweden's total hydropower production.

The oldest power plant still in operation is Hemsjö Övre in Mörrumsån, commissioned in 1907.

Open-cycle gas turbines (OCGTs)

We own and operate seven open-cycle gas turbines (OCGTs) in the South of Sweden, with a combined installed capacity of 500 MW.

The largest machine is G12 in Halmstad, commissioned in 1993. The other OCGTs were commissioned between 1971 and 1974.

The OCGTs are part of the Swedish disturbance reserve and run on light fuel oil.
